Remark

R1-Spec Titanium Catback Exhaust for 2022+ Subaru WRX by Remark Developed for those seeking a light weight high flow single exit exhaust system. This full Titanium system only weighs 16 lbs (w/ resonator), which is ~22 lbs. lighter than the OE exhaust. The R1-Spec features 3.0" mandrel bent piping, high flow straight through muffler, and 4.5" slant cut tip. The piping layout favors an optimal flow path to reduce the amount of restriction. Available with or without a resonator located on the midpipe. Select the resonated version to reduce the overall loudness of the system. Bolt-in silencer available separately in two internal pipe sizes. No unneeded pie cuts with our systems. Many enthusiasts like the look of pie cuts but in our opinion the aesthetic is not worth the potential for failure, and added exhaust gas turbulence. The use of pie cuts was a solution to create a bend when bending is not an option or the bend radius is too tight. For most front engine, rear exit exhaust systems, there is no need for pie cuts.
